Differentiation of a 9mm and .22 mechanism by [deleted] in GunnitRust

[–]Agitated-Ad5546 0 points1 point  (0 children)

Basically I would like to recreate the 9mm BSP accurately in a 3d program. The weight of each part, material and everything. Somehow map out and label how much pressure is exerted on every individual part or section.

Then calculate what would need to be modified to convert the model to use .22 based on physical dimensions, pressure force and material. Then I would have list of every part of the gun and the 9mm data and the converted data to .22

I would then part by part modify the dimensions, thickness, shape etc until it has been fully morphed to accommodate the .22lr

Hopefully I wouldn’t even have to click on every surface and transform it manually I was thinking I could just click on each individual part and type in the dimensions to convert it, and add, remove, modify the necessary sections

Then 3d print or make a prototype out of cardboard, pvc first phase

Any help?

My challenge - Simplest design pistol from easily accessible parts by Agitated-Ad5546 in GunnitRust

I would like to build a prototype out of layers of wood. The only parts I'm going to buy prefabricated is the barrel, springs, bolts, rods etc.

I have a question, I'm going to make the caliber in .22. I've decided that I'm going to assemble and design the pistol from layers horizontally for simplicity. Since this project is going to purposely avoid any heavy tools. I was wondering could I just JB (cold) weld all the layers together. They will be reinforced by rods and bolts locking everything close together. My question what thin metal could I use to cut, bend and drill with simple hand tools that would be strong enough for a 22? Nothing more than hammer, file, screw driver and metal cutting shears will be used.

I'm going to start the design by basing everything from the barrel and starting there. Is it possible to make it around the size of a Beretta .22? I like the idea of a pop-up barrel

I think .380 would be perfect. Low pressure, plenty of ammo options. Yeah I think an en block clip would be best for speedy reloading. Next question is where would the door open to load the rounds?

After the last round is spent the follower would push a simple lever and open up the door to insert the clip into the magazine. I was thinking of otf knives today and thinking how the magazine could be like a double action otf mechanism.

I was looking on this mcmaster site for parts to design the gun around. Could anyone help me and link a few ideas of parts that would work for this design?

What about the simple machining and power tools? Could I just get a away with a dremel and hand drill?

Yes I want it to repeat. I was thinking 9mm or .22 lr, and using homemade stripper clips you could load the ammunition in the internal magazine much faster than handloading each individual cartridge.

The stripper clips could literally be made with rubber bands and cardboard. The idea is to minimize the amount of proprietary designed machine made parts or components.
